I have been using this 'Lower Shield' pack for a long time because it doesn't mess with the third-person view. It is currently active in my Global Resources, but on v1.26.1.1, the shield is invisible in first-person. This transparency bug makes it impossible to use during combat.
It's a caching error. I recently modified the shield animation and changed the 3D model of another item. When a conflicting item, such as a spyglass, bow, or crossbow, is active, the animation often fails—even when using a different resource pack. 😣
The solution is to change the manifest format to version 3, which is more stable in terms of data loading and caching. Format 3 is currently in beta, but many popular add-ons and texture packs already use it. It took me months to realize that the error was simply caused by format 2, which handles loading and caching very poorly.
